Shake, rattle, and help each other along In classical statistical mechanics, the deterministic dynamics of a many-body system are replaced by a probabilistic description. Chvykov et al. work toward a similar description for the nonequilibrium self-organization of collectives of active particles. In these systems, continuously input energy drives localized fluctuations, but larger-scale ordering can emerge, such as in the flight of a flock of birds. A key concept in their theory is the… 
Field-mediated locomotor dynamics on highly deformable surfaces
TLDR
This work studies robot locomotion on an elastic membrane, a model of active systems experiencing highly deformable interfaces, and studies the curvature field mediated dynamics of a single vehicle interacting with a fixed deformation as well as multiple vehicles interacting with each other via local deformations.
A Data-Driven Statistical Field Theory for Active Matter
Modeling living systems at the collective scale can be very challenging because the individual constituents can themselves be complex and the respective interactions between the constituents are not
Criticality-Driven Evolution of Adaptable Morphologies of Voxel-Based Soft-Robots
TLDR
A task-agnostic approach for automatically designing adaptable soft robotic morphologies in simulation, based on the concept of criticality, which confirms that criticality is indeed a good indicator for the adaptability of a soft robotic morphology, and therefore a promising approach for guiding the design of more adaptive voxel-based soft robots.
Physical mechanisms of the dynamical patterns and non-equilibrium processes of self-driven particles in an ASEP network affected by a finite external particle source
Abstract When confronting complexity science, complexity systems indicating evolution regularities are addressed due to their nonlinearity, uncertainty, emergence and self-organization. Among them,

Tuning the Random Walk of Active Colloids: From Individual Run-and-Tumble to Dynamic Clustering.
TLDR
The experimental realization of tunable colloidal motion that reproduces run-and-tumble and Lévy trajectories is reported, utilizing the Quincke effect to achieve controlled sequences of repeated particle runs and random reorientations.
Programmable self-assembly in a thousand-robot swarm
TLDR
A system that demonstrates programmable self-assembly of complex two-dimensional shapes with a thousand-robot swarm is reported, enabled by creating autonomous robots designed to operate in large groups and to cooperate through local interactions and by developing a collective algorithm for shape formation that is highly robust to the variability and error characteristic of large-scale decentralized systems.
Large-scale vortex lattice emerging from collectively moving microtubules
TLDR
This study reports experiments in which microtubules are propelled by surface-bound dyneins, providing evidence for the existence of previously unsuspected universality classes of collective motion phenomena.
Drive-specific adaptation in disordered mechanical networks of bistable springs
Systems with many stable configurations abound in nature, both in living and inanimate matter. Their inherent nonlinearity and sensitivity to small perturbations make them challenging to study,
Least-rattling feedback from strong time-scale separation.
TLDR
This paper quantitatively deriving the temperature landscape for a general class of overdamped systems using a path-integral technique, and illustrates in a simple dynamical system how the attraction to low effective temperature has a fine-tuning effect on the slow variable, selecting configurations that bring about exceptionally low force fluctuation in the fast-variable steady state.
Particle robotics based on statistical mechanics of loosely coupled components
TLDR
A stochastic robotic system shows deterministic behaviour—such as locomotion, object transport and phototaxis—from the collective motion of many loosely coupled disk-shaped ‘particles’ that perform only volumetric oscillations.
Ramifications of disorder on active particles in one dimension.
TLDR
It is found that in a system with many interacting particles, disorder in the potential leads to strong clustering, and it is shown that the mean cluster size scales with the system size, in contrast to nondisordered systems.
Optimized flocking of autonomous drones in confined environments
TLDR
This paper numerically demonstrated that the induced swarm behavior remained stable under realistic conditions for large flock sizes and notably for large velocities, and showed that coherent and realistic collective motion patterns persisted even around perturbing obstacles.
A robot made of robots: Emergent transport and control of a smarticle ensemble
TLDR
It is shown experimentally and theoretically that directed drift of such a supersmarticle could be achieved via inactivation of individual smarticles and used this phenomenon to generate endogenous phototaxis and suggest that the smarticle model system may aid discovery of principles by which a class of future “stochastic” robots can rely on collective internal mechanical interactions to perform tasks.
Critical phenomena in active matter.
TLDR
The unified colored-noise approximation is exploited to map the nonequilibrium active dynamics onto an effective equilibrium one, and the evolution of the second-order critical point as a function of the noise parameters: the correlation time τ and the noise strength D.
